Factors Influencing Seed Germination of Sorbus pohuashanensis Hedl
Seed development traits of Sorbus pohuashanensis are discussed with special regard to factors influencing seed germination.The purpose of this research was to provide additional data for to suggest a method of improving seed germination in S.pohuashanensis.The limiting factors for seed germination are embryo developmental stage,seed coat (naked embryo germination was significantly higher than for intact seeds),seed hydration,and germination temperature.These results infer that for S.pohuashanesis,ptimum germination requires earlier seed collection (before dormancy intensifies),seed hydration sufficient for respiration to take place,and lower germination temperature than room temperature.
